Abstract

L'invention porte sur un fil chauffant électrique, qui comprend une couche isolante externe, un fil de détection de température, une couche isolante interne et un cœur chauffant à brins multiples, disposés en séquence de l'extérieur à l'intérieur. Le cœur chauffant à brins multiples est formé en torsadant au moins deux cœurs chauffants à brin unique, et le cœur chauffant à brin unique est formé par enroulement d'au moins un fil chauffant sur la périphérie d'au moins une fibre. La configuration structurelle du fil chauffant électrique résout le problème qui est que le fil chauffant électrique existant ne parvient pas à satisfaire aux exigences de puissance quand il est utilisé dans un produit chauffant électrique de forte puissance ou qu'il est utilisé dans un produit chauffant électrique basse tension ; cependant, la résistance à la traction, la résistance à la fracture et la résistance à la conduction de chaleur du fil chauffant électrique sont améliorées, de façon à prolonger ainsi la durée de vie du fil chauffant électrique.
